Differential response of Brassica juncea cultivars to Al; consequences for chlorophyll a fluorescence, antioxidants and psb A gene
The present study was undertaken to identify the aluminum (Al) tolerant cultivar of Brassica juncea. We examined the changes in antioxidant enzymes, proline level, chlorophyll a fluorescence and psb A gene expression at vegetative and reproductive growth stages of B. juncea cultivars (Bio-902, CS-14...

| description | The present study was undertaken to identify the aluminum (Al) tolerant cultivar of Brassica juncea. We examined the changes in antioxidant enzymes, proline level, chlorophyll a fluorescence and psb A gene expression at vegetative and reproductive growth stages of B. juncea cultivars (Bio-902, CS-14, Pusa-Tarak and Laxmi). The selected cultivars were exposed to soil (pH 5.2) supplemented with Al (0, 50, 100 and 150 mg kg−1). We observed the lowest decline in photosynthetic efficiency (ΔF/Fm′), ETR, PPFD values and psb A expression to Al stress in the cultivar Bio-902 (tolerant cultivar) followed by CS-14 and Pusa-Tarak whereas the highest decline was observed in the cultivar Laxmi (sensitive cultivar). The improved performance of the cultivar Bio-902 under Al stress was accompanied by an increase in proline level, CAT and APX activities but without any increase in SOD activity. However, significant increase in SOD activity was observed in Laxmi. |
